YouTuber horseattack has managed to construct a printer made of Legos.  He describes his work: “Lego felt tip 110″ printer connected to an Apple Mac. This is not a kit you can buy and does not use mindstorms. I designed/built/coded it all from scratch including analog motor electronics, sensors and printer driver, the USB interface uses a “wiring” board.” Now watch the magic unfold in the video above.
